With reference to FIGS. 1 and 2, a framing system 100 can be configured to support panels 200. In some environments of use, the panels can be supported so as to be offset from an existing interior residential or commercial wall or ceiling. Various embodiments of the system 100 described herein can be used to support a variety of panels 200, which may include, for example, substrate materials configured to receive a field finish or decorative panels.

One example of a substrate material is drywall. Examples of a decorative panels include wood veneer and porcelain panels. Other materials can also be used.

In some embodiments, the system 100 can provide a strong, thin, and light weight framing system for a wall. The system 100 can allow a user such as a tenant of a residential or commercial property to change the aesthetic appearance and shape of a room without modifying the existing walls which may be structural and/or may include electrical wires or pipes or other plumbing fixtures.

In addition, some embodiments can provide space between the wall panel system 100 and the existing wall such that the space can be used to accommodate electrical wiring, plumbing, acoustical blanket, lighting, or other materials the tenant may wish to hide from view. In some embodiments, the components of the system 100 can be assembled into a frame only approximately ¾″ thick, minimizing overall thickness of the resulting wall and thus minimizing the reduction in the size of the room in which the wall panel system 100 is installed.

FIGS. 1 and 2 illustrate an embodiment of a modular wall panel system 100. In some embodiments, the wall panel system 100 can be configured to support panels 200 which are visible to occupants of the room in which the wall panel system 100 is installed. The wall panel system 100 can include various components which may include, for example, various rails including, for example, main rails 300, outside corner rails 500, inside corner rails 600, and edge rails 700. In some embodiments, rails can be configured to comprise the corner or edge of the wall panel system 100, described in greater detail below with reference to FIG. 7.

In some embodiments, components modular wall panel system 100 can be configured to couple to one another to form a free-standing or supported frame for supporting panels 200 and/or other devices. For example, in addition to supporting panels 200, the modular wall panel system 100 can be configured to couple to an existing wall. In some embodiments, the system 100 can be mounted at ceiling and floor for support with no attachment to penetrate the existing wall surface. In some embodiments, the modular wall panel system 100 can be configured to couple to an existing ceiling and support panels 200 offset (e.g., downwardly) from the ceiling.

FIG. 2 illustrates a perspective view of an assembly of main rails 300 forming a junction 400, with panels 200 installed onto the main rails 300. In some embodiments, as illustrated in FIG. 2, a junction 400 can include the intersection of a rail such as a main rail 300 arranged vertically and another rail, such as another main rail 300, arranged horizontally. A main rail 300 is one type of rail which can be configured to support panels 200, other rails can also be used. In some embodiments, as noted above, rails can be configured to be oriented either vertically or horizontally.

FIG. 3 illustrates a perspective view of the panel engaging side of the junction 400 of FIG. 2. In some embodiments, rails can be configured to support panels 200 on the panel engaging side of the rails. In some embodiments, each rail can include a panel engaging portion 305 configured to be engageable for supporting at least one panel 200. The panel engaging portion 305 can be smooth and flat or it can incorporate surface features such as knurls, slots, or other patterns of raised ridges to provide additional engagement with panels 200. In some embodiments, the panel engaging portion 305 can include a generally planar mounting surface configured to accept at least one fastener 800, which can include for example, stainless steel sheet metal self-tapping screws, or other types of fasteners.

In some embodiments, the main rail 300 can be constructed of a material, which may include, for example, aluminum, capable of accepting fasteners 800. In some embodiments, fasteners 800 can be utilized to fasten the panels 200 to the rails. The fasteners can be installed through the panel 200 and into the panel engaging portion 305. In some embodiments, the panel engaging portion 305 can be about 1.5″ wide (e.g., in a direction perpendicular to the longitudinal direction of the main rail 400) to mimic the width of a “2×4” stud often used in construction. In other embodiments, different widths can be used to support a variety of panels 200. In some embodiments, the main rails 400 can have generally or substantially uniform cross sections and thus can be made from extruded aluminum. However, main rails 300 formed from extruded aluminum can have some feature that disrupt the generally or substantially uniform cross sections, using post-extrusion machining techniques, such as drilling, milling, cutting, punching, etc. which are well known in the art.

In some embodiments, rails, and as illustrated in FIG. 3, main rails 300, can include a panel engaging portion 305. In some embodiments, main rails 300 can include a first side 310 and a second side 320 on opposite sides of the panel engaging portion 305. In some embodiments, a first side 310 can include a first channel 311 comprising a first sidewall 315 and a second sidewall 316. In some embodiments, the first sidewall 315 and second sidewall 316 can be substantially parallel to the mounting surface of the panel engaging portion 305.

In some embodiments, a second side 320 can include a second channel 321 wherein the first channel 311 and second channel 321 are facing away from each other. In some embodiments, the first channel 311 and second channel 321 can be configured to accept additional components of the modular wall panel system 100, which can include, for example, a gusset 900 or an angle 1200, which are configured to couple components of the modular wall panel system 100 together.

In some embodiments, the first channel 311 and second channel 321 can be configured to accept a gusset 900. The gusset 900 can be configured to be couplable to multiple components of the modular wall panel system 100. In some embodiments, a gusset 900 can comprise a piece of sheet metal. In some embodiments, a gusset 900 can be substantially triangular. In some embodiments, a gusset 900 can be configured to slide within a first channel 311 or second channel 321 of a vertically oriented main rail 300 and also within a first channel 311 or second channel 321 of a horizontally oriented main rail 300.

In some embodiments, a gusset 900 can help to maintain a substantially perpendicular relationship between a vertically oriented rail and a horizontally oriented rail. In some embodiments, a gusset 900 can be affixed to a rail via at least one fastener 800. In some embodiments, the first channel 311 or second channel 321 of the rail and the gussets 900 can be configured to have a friction fit when the gusset 900 is inserted into a first channel 311 or second channel 321 of the rail in order to affix the gusset 900 to the rail.

In some embodiments, the standoff 1000 can be configured to be adjustable in length, allowing the installer to change the offset between the rail and the existing wall during installation. The adjustment can allow the installer to gain access behind a partially constructed wall to finish the installation of the system 100. In some embodiments, the standoff 1000 can include means for locking the standoff at a particular offset length. In some embodiments, a fastener can serve as means for locking the standoff 1000 into a desired length.

In some embodiments, a standoff 1000 can include a rail coupling member 1010 configured to couple to the wall engaging portion 330 of the rail. In some embodiments, the rail can include a rear channel 331 formed in the wall engaging portion 330 of the rail. The rail coupling member 1010 can be configured to fit within the rear channel 331 of the rail. The rear channel 331 can be configured to accept the rail coupling member 1010 of the standoff 1000. In some embodiments, the rail coupling member 1010 can be slid within the rear channel 331 until the desired location is achieved.

In some embodiments, a standoff 1000 can also include a wall coupling member 1020. The wall coupling member 1020 can be configured to be coupled to an existing wall. In some embodiments, the wall coupling member 1020 can include at least one aperture configured to accept a fastener 800. In some embodiments, a fastener 800 can be utilized to couple the standoff 1000 to the existing wall.

In some embodiments, a sleeve member 1030 can be configured to accept the ends of the members 1010, 1020 of the standoff 1000, members 1010, 1020 to slide within the receiving portion 1030 so as to allow the distance between the rail and the existing wall to be varied during construction. Optionally, the receiving portion 1030 can include a slot 1035 through which fasteners (not shown) can extend to engage the members 1010, 1020. In some embodiments, a standoff 1000 can be configured to engage two rails instead of a single rail and an existing wall.

As illustrated in FIG. 4, a bracket 1100 can be utilized to couple at least one vertically oriented rail to at least one horizontally oriented rail. For example, a bracket 1100 can couple multiple rails together and add structural integrity to the wall panel system 100. In some embodiments, the bracket 1100 can be configured to engage the wall engaging portion 330 of each rail. In some embodiments, the bracket 1100 can be configured to follow the contours of the wall engaging portion 330 of each rail. In some embodiments, the bracket 1100 can be configured to be coupled to the wall engaging portion 330 of each rail via at least one fastener 800. The bracket 1100 can include at least one aperture to accept a fastener 800. In some embodiments, the width of the bracket 1100 can be optimally dimensioned to fit within the rear channel 331 of a rail.

FIG. 5 illustrates a top view of the bracket of FIG. 4. In some embodiments, the bracket 1100 can include a first rear channel engaging portion 1110 configured to engage the rear channel 331 of a rail.
